In the 1998 Windstar, the ABS system helps prevent the wheels from locking up during braking, ensuring better control and stability while braking. When the ABS warning light is illuminated, it means the ABS system is disabled, and the vehicle's brakes will function without ABS assistance until the underlying issue is fixed.
If you see the red exclamation mark on your 1998 Windstar van, it's important to have the problem diagnosed as soon as possible to ensure safe and effective braking performance.
